17 Claims.

This invention relates generally to harvesting machines and moreparticularly to corn harvesters of the type that is mounted on the bodyof a tractor, and has for its principal object the provision of a novel`and improved corn harvester, which is considerably lighter in weightand consequently less expensive than vmachines now known to those`skilled in the art, but in which neither efliciency nor durability issacriced. In the accomplishment of this object I have provided a cornharvester of the picker sheller type in which anl unusual degree ofcornpactness and simplicity' is obtained by rigidly mounting theshelling cylinder directly'underneath the upper end of thegathering andpicking unit in a transverse position, so that the entire machine is oneunitary structure. This structure is mounted on the tractor for pivotalmovement about the axis of rotation of the shelling rotor, so thatvertical adjustment of the forward ends of the gatherers is obtained byrocking the entire machine about the shelling rotor axis.

Relating to the provision of a corn harvester of lighter weight, afurther object of this invention has to do with the provision of asimplied gatherer unit in which the usual gatherer chains are eliminatedand a single device substituted therefor, which combines the functionsof gathering the stalks and also conveying the snapped ears to the rearend of thegathering unit. In the accomplishment of this object, I haveprovided a pair of augers disposed side by side above the snappingrolls, and having overlapping heli- -calvanes, which cooperate to moveAthe stalks rearwardly between the snapping rolls. The augers aredisposed in longitudinally extending troughs, into which the ears ofcorn fall as they are snapped from the stalks, and along which theangers convey the snapped ears of corn.

A related object has to do `with the provision for disposing of anycornstalks that may break oiT and lie along the top of the` augers and'between the helical blades thereof. In the accomplish-ment of thisobject, certain of the flights of the helical blades are provided withcooperative notches, which engage a cornstalk and force `it downwardlybetween the auger blades and int-o Still another object'is'con'cernedwith the provision of means for preventing snapped ears from lyingbetween the two snapping rolls and parallel thereto. This featurereduces the amount of corn lost at the snapping rolls by prematureshelling;

Another object relates to the provision of a novel and vimprovedcleaning and separating device, through which the shelled cobs and husksare passed after they leave the shelling cylinder,l

to remove any kernels that may have been discharged therewith. A relatedobject has to do with the provision lof means in the trough' foractively clearing the cobsfand husks away from the cob discharge openingin the shelling housing vand to assist in separating the kernels vofcorn fromthe husks and trash. In the accomplishment of this object,apair ofv augers are/pro- 'vided in the cleaning trough, for moving thetrash transversely vaway from the cob discharge opening, after which thecobs 'andftras'h are 'subjected to the action of a pair of feeder bladesfor stirring the trash to separate therefrom'any kernels of corn whichmay be entangled therewith. Still another related yobject is to providea pair of cooperative knife blades for chopping any trash that ftends toclog in the corner of the discharge` opening in the sheller housing.

A further object relates tothe provision of a novel and simplified grainconveyor from the grain trough in the sheller housing to a wagon ortruck traveling along with the tractor for rel ceiving the grain.

Another object relates to the provision of va nalcleaner at the end ofthe grain conveyor, for; separating any silksI or other trash'frorny thecorn .before the latter -is discharged into the wagon.

These and other objects and advantages of my invention will be apparentto those skilled in the 'art after a consideration' of kthe followin'sr`description in which reference is had to theV drawings appended hereto,in'which i Figure l'is a plan view of a corn harvester embodying theprinciples of my invention, mounted on the side of a tractor; y ljFigure 2 is a side elevational view of the harvester and tractor;

to the provision of a simplified framework for the gatherer unit, whichalso serves as an enclosure for the drive gears for the snapping rolls,requiring only a pair of upper and lower enclosure plates to completethe housing.

Figure 8 is a fragmentary elevational view', I drawn partly in section,showing the rear end..

and showing the details of the nal cleaner at the end of the elevator.

Referring now to the drawings, the tractor, in-

dicated generally by reference numeral I8, is of the conventionaltricycle type comprising a nar row longitudinallyextending l body IImounted 0n a pair of closely spaced front dirigible wheels I2 and a pairof widely spaced rear traction wheels I3, one' of which is shown inFigure 1'. The rear traction wheels I3 are mounted in the usual manneron axles I4 journaled in a pair of laterally extending rear axlehousings I5. n

The corn harvester, indicated generally by reference numeral 20,comprises a transversely di'sposed housing 2I, having a'forwardly anddownwardly extending gatherer unit 22 rigidly fixed thereto and formingaunitary structure therewith. The implement is'carrie'd adjacent oneside-of the tractor body II intermediate' thereof between the forwardand rear wheels I2,v I3on .shaft 44 are journaled in a pair of bearings46 which are supported on the transverse frame 4member 4I, and theshafts extend behind the bearings 4BA and support at their rear ends, apair of-bevel. gears 41. The bevel gears 41 mesh with a pair ofcooperative bevel gears 48, fixed on a transverse drive shaft 49, whichis journaled vinl a pair of laterally spaced bearings (not shown) onfthetwo longitudinal frame members 31, 38

vand extends through the member 38 to a drive sprocket at the side oftheimplementadjacent the'tractor. Inasmuchas ,the diameter of the vbevelgears 41, 48'are less'than the vertical thickness of the framemembers'31, 38'and the transverse members 39, 4I, the frame members serve toenclosethe gears on fourl sides and require only a pair of upper andlower enclosure plates 55, 5'to form a completegear housing, as isevident in Figure 3. Thegears`41, 48 are arranged a transverselydisposed pipe beam'23, rigidly supported in' a pair of laterally Jspaced`supporting plates 24, secured tothe sidesof thetractor-body by bolts25. The supporting beam 23 extends laterally from the tractor body andcarries apair of upwardly and rearwardly extending arms 26 rigidly fixedthereto. f Y n Journaled'at opposite ends, respectively,in'the lupperend ofthe arms 26-is la transversely :disposed shaft 21,r which is thesupporting shaft for the shelling rotor 28 (see Figure 3). The shellingrotor 28 is preferably in the form of a cylindrical drum havingVradially extending cob l.engaging lugs 29,butV anyconventional -form ofshelling rotorV is intended to lie within the scope f` of the presentinvention. lThe shelling rotoris disposed generally coaxially with acylindrical Sheller housing 30, the lower half of which is in the formof a screen or cage 3I, through which the shelled kernels of corn fallwhile the cobs,

longitudinally disposed supporting frame'36 comprising a pair oflaterally spaced longitudinally extending tubular frameinembers 31, 38Vof rectangular cross section, rigidlyfconnecte'das'by welding, 4at theupper end to 'amain transverse beam member in the form of Va pipe 39,having a pair of flanges 40 at opposite ends thereo'f,re spectively,which are rigidly xed, as by'bolting, to the` end plates 35. Thelongitudinal .jframe l,members 31, 3 8 are also interconnected by'meansof a structural channel member 4I disposed ahead .to drive the snappingrolls 42, 43 in opposite directions of rotation, as indicated by thearrows in Figure 4, to pull cornstalks downwardly therebetween and snapthe ears therefrom in a well- -known manner. The forward ends of thesnap- -ping rolls 51 are tapered ina customary manner to' receivetherebetween 'the cornstalks as `the implement advances inthe field. v

JA pair 'of' auger conveyors 60, 6I are disposed above thesnapping'rolls 42, 43 in generally parallel relation thereto and toeachother, and comprises a pair of parallel shafts 62, on each of'which`is wound a helical blade 63. The-shafts 62 are journaled at their lowerends in' suitable 'journal bearings 64^supported on the forward ends ofthe frame members 31, 38, respectively,

jandanother pair 'of journal bearings 65 mounted yon theback sheet 66 ofthe housing. The shafts 62 `are spaced laterally a distance less thanthe snapping rolls. The auger blades 63 of the two augers are wound withthe same pitch but in reverse direction. That is to say, the blade 63 ofthe left-hand auger 60 is Wound as a left-hand 'screw While the blade 63on the right-hand auger 6I is wound as a right-hand screw, with theresult that when the two augers are turned in opposite directions,'bothof the blades 63 have a vrearwardly propelling effect upon thecornstalks.

The augersare rotated in opposite directions and 'at the same `speed ofrotation, by means of a pair of beveled gears 61,V mounted on the rearends of the shafts 62 behind the back sheet 66. Gears '61 are disposedin mesh with a pair of bevel driv- -ing gears 68,y mounted in opposedrelation upon `a transverse drive shaft 69, journaled in laterallyspaced bearings 10 in an extension housing 1I i'lxed to the back Vplate6B. An outboard bearing 12 is attached to the housing 39 and supportsvthe outer end of shaft 69.

It frequently occurs that a cornstalk will break "off above they augers60, 6I and lie upon vthe overlapping blades 63. In order to get rid of'and upwardly over the augers 60, 6|.

' to be acted upon .by the snapping rolls.

these broken stalks before they are carried rearwardly into the `snellercage, several of the turns of eachof the blades 63 at the intermediatepontion of the augers are trimmed off; as indicated in Figure 4, at 15.of the two blades are timed to receive between them a cornstalk, asindicated at 16, and since the rotation of the blades 63 is such thatthe inside edges thereof move downwardly, the cornstalks are engaged bythe cut-away portions and forced downwardly below the augers intoengagement with theV snapping rolls. Without these cut-away portions; Ihavefound that many pieces of broken corn'stalks which fall on top ofthe augers 60, 6| are conveyed rearwardly `and tend to clog the shellingcage, but I have found that the above described device is very eifectivein disposing of the cornstalks and preventing them from being conveyedinto the cage.

'.A pair of guard plates 11,L 18 are disposed between the 'snappingrolls 42, 43 and the augers 60, 6|, respectively.` The guard plates 11,18 extend longitudinally of the picking unit and lie on the tops of thelongitudinal frame members 31, 38, respectively, and arer fixed theretobyfa series of clips 19. Each of the guard plates extends inwardly overits adjacent snapping roll, curving over the latter in closely spacedrelation thereto, and terminates in a longitudinally extending inneredge that is preferably sinuo'us in form. The inner edges of the twoplates 11, 18 define a sinuous slot therebetween, which is generally inregister -with the space between the snapping rolls and substantially ofuniform width. The guard plates 11, 18 effectively prevent ears of cornfrom being caught between the two snapping rolls after having beensnapped from the stalks and then being forced through `the rolls orshelled'by the lugs" on' the snapping rolls. By making the slot 80sinuous or zig-zag in form, with the curves of the slot vshorter thanthe length of an average ear of corn, the latter do not tend to lielongitudinally within the slot and slide rearwardly therein, but areheld up in a position in which the ears can be engaged by the blades 63and thrown outwardly on either side of the snapping rolls into one of apair of troughs 85. n

The troughs 85 are formed by a pair of sheet metal side walls 86 whichextend longitudinally of the frame members 31, 38 and curve outwardlyThe longitudinally extending lower edge of each' of the side walls 86 issecurely Vattached to the outer edges of the plates 11, 18,respectively. Since the vaugers 60,` 6| lie longitudinally within therearwardly extending troughs 85, the augers act not only as gatherersforthe cornstalks but also as conveyors for the ears of corn, and engagethe latter'within the troughs 85 to move them -rearwardly to an aperture81 inthe bottom of 36 is supported a gatherer lpoint 92, which can be ofany -suitable'shape, for the purpose of lifting lodged stalks from theAground to permit them These cut-away portions 15 4,

The ears of corn are introduced into the shelling cylinder at the innerend of thelatter through the feeder -openingl and are propelled axiallyoutwardly .throughthe cage by Ythe action of the shelling beater 20 in awell-known manner. The kernels are shelled from the cobs by the actionof the ears rubbing against each other and the shelled kernels dropdownwardly through the cage 3| and are collected in a conveyor troughthat extends beneath the cage 3| and generally parallel to the axisthereof. A fan housing 96 is supported on the shelling housing 30immediately aheadofthe latter, and disposed within the housing 96 is afanrotor 91 mounted on a shaft '98. The fan housing 96 has a dischargeoutlet 99, which directs a blast of air rearwardly beneath the shellingcage 3| and substantially perpendicular to the axis of the latter. Thus,as the corn falls into the troughl 95, it is subjected to the blast ofair from the fan,which removes dirt, silks, or other trash that fallfrom the cage, and the latter are carried by the air blast rearwardlythroughA a discharge duct |00 having a downwardly turned dischagedaperture |0| at the rear end thereof, for discharging the trash to theground at the side of the tractor.

The outer end of the cylindrical shelling housing 30 is provided with acob discharge opening ,32, through which the cobs and husks are forced,and husks out vofv the shelling cage in a manner well-known tothoseskilled in the art and insures that the cobs are sufliciently shelledbefore they `are discharged.

The cobs, husks and silks are discharged into a perforated cleaningtrough V| I0, which extends transversely behind the shelling cage andsubstantially parallel to the axis ofthe latter. The trough ||0formsthelower part of a housing having a roof III, for preventing the trashfrom blowing out of the trough before it is properly cleaned. The trashpasses axially through the trough and isdischarged from an aperture ||2in the rear thereof adjacent the inner end of the housing. Any shelledkernels of corn which may be carried out of the shelling cage with thetrash,

pass ythrough perforations I4 in the cleaning ltrough 0 and drop uponthe top wall of the air discharge duct-|00, over which they slideforwardly into the trough 95. The top of the discharge duct |00 isspaced below the shelling cage 3l to provide a ,'slot` ||3 to allow thepassage of the kernels.`

The trash and cobs are moved longitudinally through the cleaning trough||0 from the entrance opening 32 to the discharge opening||2 'by meansof a pair of beaters H5, ||6 arranged longitudinally in the trough ||0and each co-mprising a supporting shaft ||1, journaled in bearings ||8in opposite end walls of the cleaning trough. A helical blade ||9 iswound-upon -each of the shafts ||1 directly Vbehind the opening 32 andterminating at a point behind the inner edge of the opening 32. Theinner end of each of the helical blades l| I9 is connected to the end ofa straight blade |20, forming a continuation thereof and extendingaxially to the opposite end wall ing straight :'blacle':` |2| is'flxedtojeachof; the shafts I |1. opposite'the Vstraight :blade 1|20,and this second blade |2| extends outwardly. along the shaft untilit'abuts the helical bladel |95 The two helical blades ||9.are' bothwound inthe same direction-and the shafts ||1 are turned in the samedirection of rotation and"cons`equently, the cobs and trash are quicklymoved :bythe blades away from in front of the-opening 32 to clear thelatter and thusato prevent-clogging intheopening.

In order to .prevent stalks and long leaves and husks from hanging overthe inner edgerof the opening 32, a knife bladel |25 is disposed.diagonally across the innerlower corner'of the yopening as indicatedinFigures 5 and 6. f Long stalks and leaveswhich are moved transverselyacross the opening bythe blade |I9'of the forward beater 5, are dragged:over the sharp -edgeof the knife 25 and are cut off. Inorderto provide a`positive shearing action.- a knife'blade section |26 is provided on theforward beater1||5.V 'Ihis knife section |26 is*` inthe form ofI agenerally triangular blade curvedcylindrically to follow the outer edgeofthe'blade ||9 to its point of termination with the` straight blade.and having a helically formed knife edge |21 .adapted to cooperate withthe knife-blade |25 in afshearing 'contact therewith. f

Attached tothe inner end of the grain trough 85 and vforming acontinuation thereof, isa conveyor tube |30, which is rigidly attachedytothe inner end plate'35 ofthe housing of the harvesting implement andextends transversely -under ythe body Il of the tractor lll, and isrswingable vator .tube |33r,which is supportedlon azbracket |34,lswingably connectedto a` supporting link .I 35 by a transverse.pivotlbolt |36., The lower end of the link |35 is pivotally, connectedbyfaxbolt |31 to a draft frame |38', which is .fixed by bolts |30 to therear side of the'traotor axle housing 5.

Since the smoporting link |35 is freeto pivot about the bolts |36.` |31,the elevator tube |33 can move fore and aftasthe cornvharvesteris swungabout the axis of the shaft`u21to raise and lower the gatherer points62.] This swinging adjustment is accomplished vby meansof a handactuatedlever |40. which is'frigidly xed Itothe body of the housing 30.

It

then slides forwardlyV andfdownwardly/through .the tube I 68 and dropsto the groundzahead rof the wagon |55. It will be noted-that the'diameter of. the tube I68-is less than the diameter. of ithe tube |33and thereby providesV space between-.the side'wallsz-I63for thekernelsof corn to'drop. on either side'of the tube :|68 to the spout |62; The

Power for operating the entire harvesting implement is supplied by adrive chain which connects a, main drive sprocket |16 on the inner endof the cylinder shaft 21 with a detachable sprocket |11 which issuitably mounted on the belt pulley |18 of the tractor. Adjacent to thedrive sprocket |16 on the cylinder shaft 21 is a sprocket |19, whichdrives the sprocket 50 on the snappingv roll drive shaft 49 through achain |88. The shaft |3| of the transverse conveyor is driven from theshelling rotor shaft 21 by means of a chain |8| trained around asprocket |82. The gathering augers 60, 6| are driven through the shaft69 by means of a chain |83 trained arounda sprocket |84 on the outer endof the shaft 69. The chain |83 is also trained around a pair ofsprockets |85, |88 mounted on a pair of idler shafts |81, |88,respectively, which are fixed to a mounting plate |89 rigidly fixedtothe end plate 35. It will be noted that the chain |83 is trainedaround the sprocket |85 to drive the latter inthe opposite direction tothat of the shelling rotor shaft 21.A A second sprocket |90 is mountedon thershaft `VI 81 and. drives the fan shaft 98 through a chain |9|also in the opposite direction of rotation to that of the shellingrotor. A third sprocket |92 on the outer end of the shaft |81 drives thetwo beater shafts [l1 through a chain |93 trained around a pair ofsprockets |94 on the shafts ||1.
